Home is more than just a word;it represents a profound emotion for every individual. Hospitalization often deprives the geriatric population of this comforting environment due to their deteriorating health. However, with technology-oriented automated and monitored assistance systems, older adults can receive adequate care and support at home, allowing them to lead independent lives. This approach requires robust systems to assess relevant information, process data in real time, and provide dynamic solutions when necessary. Ambient Assistive Living (AAL) systems are crucial to improving the quality of life for older adults, despite the challenges they pose. India, with its diverse cultural and demographic landscape, presents unique challenges and opportunities in geriatric care. While older adults aspire to live in their own homes, they often face barriers such as limited access to affordable and user-friendly technology. However, the Indian older adult population also presents opportunities for innovation and tailored solutions that consider cultural nuances and family dynamics. This article provides an overview of available geriatric assistance technologies, highlighting their advantages and disadvantages. It critically analyzes geriatric care in the Indian context, focusing on the specific challenges and opportunities presented by the country’s cultural and demographic diversity. By exploring potential integrated solutions, this article aims to enhance healthcare delivery and improve the quality of life for older adults in India. © 2025 Taylor & Francis Group, LLC.

rejecting outliers before applying classical robust methods is a common approach to increase the success rate of estimation, particularly when the outlier ratio is extremely high (e.g. 90%). However, this method often relies on sensor- or task-specific characteristics, which may not be easily transferable across different scenarios. In this paper, we focus on the problem of rejecting 2d-3d point correspondence outliers from 2d forward-looking sonar (2d FLS) observations, which is one of the most popular perception device in the underwater field but has a significantly different imaging mechanism compared to widely used perspective cameras and LidAr. We fully leverage the narrow field of view in the elevation of 2d FLS and develop two compatibility tests for different 3d point configurations: (1) In general cases, we design a pairwise length in-range test to filter out overly long or short edges formed from point sets;(2) In coplanar cases, we design a coplanarity test to check if any four correspondences are compatible under a coplanar setting. Both tests are integrated into outlier rejection pipelines, where they are followed by maximum clique searching to identify the largest consistent measurement set as inliers. Extensive simulations demonstrate that the proposed methods for general and coplanar cases perform effectively under outlier ratios of 80% and 90%, respectively. Copyright © 2025, The Authors.

Lithium manganese iron phosphate (LMFP) has attracted considerable interest for its superior energy density compared to LiFePO₄. Nonetheless, the practical implementation of LMFP faces challenges due to its naturally poor electrical conductivity and manganese dissolution, which arises from the Jahn-Teller effect. In this study, a comprehensive investigation of the synergistic effects of carbon coating was elucidated, demonstrating simultaneous enhancements in interfacial charge transport and structural stability. Experimental results highlight that precise control over the coating amount is a key strategy for achieving high-performance LMFP. The carbon serves as a physical barrier to avoid direct interaction between the LMFP and the electrolyte, mitigating the corrosion of Mn ions on the material surface caused by acidic components in the electrolyte. Further ex situ Xrd analysis demonstrates that optimizing carbon content reduces lattice expansion during redox reactions, thereby improving the material’s structural integrity. Consequently, the optimized sample demonstrates enhanced electrical conductivity and a robust structural framework. It achieves an exceptional discharge capacity of 138 mAh/g at 2 C, along with outstanding capacity retention of 98.4% at 1 C after 300 cycles. This work deepens the research on carbon-coating modification and provides valuable insights into the design of olivine-based cathode materials with high Mn/Fe ratios. © 2025 American Chemical Society.

Extracellular polymeric substances (EPSs) recycled from excess sludge in wastewater treatment plant are biological macromolecules and high value-added materials, because of containing abundant characteristic functional groups. In this work, using EPSs as an intercalation agent between two-dimensional (2d) transition metal carbide and nitride (MXene) nanosheets, EPS-intercalated MXene (EPS-M) membranes were successfully constructed for reverse electrodialysis (rEd) salinity gradient energy harvesting. The interlayer spacing of MXene nanosheets in the EPS-M membranes was constrained effectively at 1.48 ± 0.02 nm regardless of environmental conditions. For the optimized EPS-M membrane with 10 % EPS mass content, the ultimate strength was 71 MPa, which was 6 times higher than that obtained by pristine MXene membrane. The typical groups such as hydroxyl and carboxyl groups present in EPS enhanced the negative surface charge of EPS-M membranes, resulting in high ion permeability and cation selectivity. The enhanced hydrophilicity induced by EPS contributed to the reduced membrane resistance. A model (0.5 M/0.01 M NaCl solutions) was used to investigate the salinity gradient power generation of sea water/secondary effluent of WWTP in rEd process with EPS-M membrane;and the maximum output power density reached 5.89 W m−2, which was 1.86 times higher than that obtained using the pristine MXene membrane. This study opens a novel application of high value-added recycled EPS, which can be considered as a cost-effective biological composite material to improve MXene 2d membrane performance compared to the macromolecules such as nanofiber and cellulose. © 2025 Elsevier B.V.

Acetaminophen and caffeine are analgesic or psychoactive drugs in human life that plays a major role in food and medicinal chemistry. Caffeine increases the efficacy of acetaminophen by improving its absorption, thereby prolonging analgesic action. Caffeine might exacerbate symptoms of anxiety if being prone to them. Taking these medications for a headache or migraine may cause problems for human life. developing a sensitive, selective, easy, quick, and economical electroanalytical approach for the simultaneous detection of acetaminophen and caffeine has been a major area of research since they typically coexist in biological fluids and oxidize at overlapping potentials. Voltammetry has become one of the most commonly used and an important method amongst the other methods due to its high sensitivity and reliability. Moreover, carbon materials, metal/metal oxides/nanoparticles, and polymer-based materials have enhanced researchers' attention for the strategy and growth of electrochemical sensors for acetaminophen and caffeine. This compilation is a comprehensive effort to address the growing need for materials and their simultaneous detection of acetaminophen and caffeine. In this study, the validation parameters (electrode surface area, catalytic activity, electron transfer kinetics, potential window, sensitivity, and selectivity) were evaluated and provided a strong foundation for evaluating the effectiveness of materials and techniques. This review highlights the most widely used voltammetric methods for simultaneous electrochemical determination of acetaminophen and caffeine, and it explains the interference effect of acetaminophen and caffeine along with similar structural components. Finally, the topic has been concluded with existing challenges and prospects.

The radio on Fiber (rOF) technique has great potential in wireless communication systems. In this paper, we report on a fundamental examination of microwave wireless access systems based on radio on Fiber. First, we designed and constructed examination systems by applying dual band (2.4 and 5 GHz) multiservice transmission systems and confirmed that there was sufficient performance through a transmission experiment. Then, application of FP-Ld (Fabry Perot Laser diode) was considered in order to reduce the system cost, and for the most part degradation of the transmission characteristics was not observed when FP-Ld was used. Finally, a BIdI (bidirectional) module which integrated Ld and Pd within one package was made to further reduce costs. By measuring the transmission performance, applying the BIdI module to rOF systems was shown to be effective. (C) 2007 Wiley Periodicals, Inc.

The standard method for detecting sentinel lymph nodes (SLNs) requires injecting radioactive material and using a gamma probe to locate them. However, this approach has several issues due to the use of radioactive material. We have developed a photoacoustic finder (PAF) that detects SLNs using only blue dye, without radioactive material. In this study, we validate the performance of PAF by comparing its detection rate with that of standard methods in 375 lymph nodes resected from 121 breast cancer patients. The results demonstrated that the SLN detection rates of the gamma probe and PAF were comparable, with non-inferiority analysis indicating that PAF's performance was not inferior to the standard detection method. These findings suggest that PAF could alleviate the issues associated with the traditional radiological SLN biopsy. © 2025, The Authors. All rights reserved.

Mn-doped SrCoO_(3-δ) Perovskite Oxides for Ethylene Production via Chemical Looping Oxidative dehydrogenation of Ethane

引用

China Petroleum Processing & Petrochemical technology 2024年第3期26卷 53-62页

作者： Li Zhi Liu Linjiao Hao daijun ren Xiaohang Shen Fangxia Li Xin Yu Anping Luoyang R&D Center of Technology of Sinopec Engineering(Group)Co.Ltd. Luoyang 471003China

Chemical looping oxidative dehydrogenation (CL-OdH) is an economically promising method for convertingethane into higher value-added ethylene utilizing lattice oxygen in redox catalysts, also known as oxygen carriers. Inthis study, perovskite-type oxide SrCoO_(3-δ) and B-site Mn ion-doped oxygen carriers (SrCo_(1-x)MnxO_(3-δ), x=0.1, 0.2, 0.3)were prepared and tested for the CL-OdH of ethane. The oxygen-deficient perovskite SrCoO_(3-δ) exhibited high ethyleneselectivity of up to 96.7% due to its unique oxygen vacancies and lattice oxygen migration rates. However, its low ethyleneyield limits its application in the CL-OdH of ethane. Mn doping promoted the reducibility of SrCoO_(3-δ) oxygen carriers,thereby improving ethane conversion and ethylene yield, as demonstrated by characterization and evaluation experiments.X-ray diffraction results confirmed the doping of Mn into the lattice of SrCoO_(3-δ), while X-ray photoelectron spectroscopy(XPS) indicated an increase in lattice oxygen ratio upon incorporation of Mn into the SrCoO_(3-δ) lattice. Additionally, H2temperature-programmed reduction (H2-TPr) tests revealed more peaks at lower temperature reduction zones and a declinein peak positions at higher temperatures. Among the four tested oxygen carriers, SrCo0.8Mn0.2O_(3-δ) exhibited satisfactoryperformance with an ethylene yield of 50% at 710 °C and good stability over 20 redox cycles. The synergistic effect of Mnplays a key role in increasing ethylene yields of SrCoO_(3-δ) oxygen carriers. Accordingly, SrCo0.8Mn0.2O_(3-δ) shows promisingpotential for the efficient production of ethylene from ethane via CL-OdH.
